Application filed July 21, 1914. Serial No. 852,273.

To all whom it may concern Be it known that 1, ARTHUR F. PINE, a citizenof the United States, residing at Castle Rock, in the county of Douglasand State of Colorado, have invented a new and useful Bolt Cutter andHolder, of which the following is a specification.

The device forming the subject matter of this application is adapted tobe employed for clipping off bolts and the like and for holding a boltor a nut while the element which cooperates therewith is being turned.

One object of the present invention is to provide a novel plungerstructure which cooperates with the jaws.

Another object of the invention is to provide a device of the type abovedescribed having bolt holding means and cutting means, the device beingso constructed that by the reversal of a part of one of the oper atinglevers, either the cutting means or the holding means, may be operativeby pressing the levers together. 1

It is within the scopeof the invention to improve generally and toenhance the utility of devices of that type to which the presentinvention appertains.

With the above and other objects in view which will appear as thedescription proceeds, the invention resides in the combination andarrangement of parts and in the 7 details of constructionhereinafterdescribed and claimed, it being understood that changes inthe precise embodiment of the invention herein disclosed can be madewithin the scope of what is claimed without departing from the spirit ofthe invention.

T11 carrying out the presentinvention there 1s provided a main lever 1and an auxiliary lever 2, the lever 1 terminating in a finger 3 and thelever 2 terminating in a finger 1. The lever 2 includes a shank 5 whichis preferably tapered. The levers 1 and 2 are equipped with ears 6through which passes a pivot element 7. The levers do not cross at thepivot element 7. On the main lever 1 there is a lug 8 into which isthreaded a screw 9, the lug or the screw, depending upon the position ofthe latter, being adapted to engage the shank 5 of the auxiliary lever 2to limit the relative movement between the levers when the free endsthereof are closed together.

The auxiliary lever 2 is a composite struc ture and includes anextension 10, the extension 10 of the auxiliary lever 2 and the mainlever 1 being provided at their free ends with suitably shaped handgrips 11. The extension 10 terminates in a socket 12, receivingremovably the tapered shank 5. At its end, the socket 12 terminates in ahook 14 having functions which will be set out hereinafter.

A latch mechanism is provided for holding the extension 10 of theauxiliary lever 2 on the tapered shank 5 thereof, this latch mechanismin the present instance embodying a lever 15 fulcrumed between its endsas shown at 16 upon projections 17 formed on the socket portion 12 ofthe extension 10. fit-its free end, the lever 15 is equipped with aninwardly projecting pin 18 adapted to engage in either one of a pair ofseats 19 formed in opposite faces of the shank 5 A spring 20 isinterposed between the lever '15 and the extension 10 and serves as ameans whereby the pin 18 normally is held engaged in one seat 19.

The invention includes a pair of arched '7 jaws 21 straddle the fingerportions gripping means. The arms of the U-shaped 3 and 4 of the leversand are-terminally provided with openings 42. Through these openings 42and through theends of theparts 3 and 4- are passed pivot elements 22.At their crowns and along their longitudinal edges,

the arched jaws 21 are equipped with cutting elements'23l The inventionincludes a fulcrum member denoted generally by the numeral 24. Thisfulcrum member 24 is a multi-part structure and its gener'aloutline willbe un- I derstood best when Fig. 4 is examined. The

' the arched jaws 21.

fulcrum member'24 lies between the arms of The fulcrum member 24embodies a block25 shown inverted in Fig. 8.. The block 25 is equippedwith openings26. Pivot elements 27 lie in the openings 26 and engage thearms of the jaws 21,

Preferably, the pivot elements are in the form of screws threaded andcounter-sunk into the arms of the jaws. In its transverse edge, theblock 25 is equipped with a slot 29. The slot 29 is adapted to receiveeyes 30 formed: at the ends of the arms of a U- shaped yoke 31 shown indetail in Fig. 7. In the eyes 30 there are openings 32 c0- operatingwith openings 33 injthe-block 25,,

1 securing elements 39 of any desired form being engaged in the openingsto hold the yoke on the block as shown in Fig. 4. The arms of theyoke'31 are provided with threaded openings 24 and in the intermediateportlon of the yoke there is an opening 35 which is of elongated orenlarged form. (Set screws 1 36 are threaded into the openings 34. The

set screws 36 engage the outer edges of guides 37, one of which is shownin Fig. 6,

I .each guide havinga flattened tongue 38 which extends intothe slot29of the block 25. Owing to this construction, the guides 37 may be movedtoward and away from each other by means of the screws 36, but cannotmove in the directionof their lengths, owing to the fact that the endfaces 40 of the guides 37 are engaged with the block 25 on each side ofthe slot 29. The inner faces of the guides 39 are grooved longitudinallyas shown at41.-

The invention includes a plunger 43 which 7 extends through the opening35 in the yoke 31 and lies in the grooves 41 of the guides 37, theplunger 43 terminating in a flat tip 44 i which registers in, the grooveor slot 29 of the block25. Theplunger 43 terminates in equipped Withseats 48.

'as shown in F i 2 the jaws being provided with openings 28 in which thepivot elements 27 are received.

The seats 48 of one jaw cooperate with the teeth 47 of the other aw aswillbe understood when Figs. 1 and 2 are noted. The seats 48 and theteeth 47 may be described briefly as a secondary gripping means.

Presupposing that the parts are positioned a, when the hand grips 11 onthe respective levers 1 and 2 are pressed together, the fingers 3 and 4will be separated, tilting the jaws 21 on their fulcrums 27 and bringingthe cutting edges 23 together, as shown in Fig. 1. The plunger 43, beingreceived between the guides 37, serves to maintain the jaws 21 in properrelation to each other. It may now be noted that by manipulating thescrews 36, the positions of the guides 37 may be altered with respect toeach other and with respect to the plunger 43, in order to compensatefor wear, and also to effect an adjustment whereby the cutting portions23 of the jaws 21 may be disposed properly with respect to each other.The plunger 43 is made of tempered steel and is resilient and laterallyflexible. Consequently, under an undue strain, the element 43 will yieldlaterall but will resume its original position after the strain hasceased. In this manner, an undue strain upon the jaws 21 may berelieved.

Presupposing that the levers are in the solid line positions shown inFig. 1 it will be seen that when the grips 11 are moved toward eachother, the cutting edges 23 of the jaws 21 will be moved toward eachother also, the gripping portions 48 and 47 of the respective jaws beingseparated, these gripping portions serving, when the structure isarranged as hereinafter described, to hold a nut, the rounded end of abolt or the like. When it is desired to use the gripping portions 47 and48, the extension 10 is removed from the shank 5 and is reversedlaterally, so that it assumes the dotted line position shown in Fig. 1.The extension 10 is offset as shown -at 49 and consequently when theextension is positioned as shown in dotted lines in Fig. 1, the leverswill be crossed on each other. It is now possible to cause the grippingportions 47 and 48 of the jaws to coactwhen the grips 11 are drawntogether. The same motion, therefore, which serves to bring the cuttingedges 23 into coacting relation serves also to bring the grippingportions 47 and 48 into coacting relation when the extension 10 has beenreversed as hereinbefore set forth.

Owing to the arched form of the jaws 21 it is possible to cut off a boltor the like at right angles to the axis of the bolt when the levers land 2 do not lie in a plane which is at right angles" to the axis of thebolt. F urther, owing to the U-shape of the jaws 21, one side of eachjaw serves to reinforce the other side thereof, the jaws being thusstrengthened and it being possible to use relatively light stock in themaking of the aws.

The fulcrum member 24: need not of necessity be used in connection withthe U-shaped jaws 21. levers are shown at and the stop mechanism appearsat 51. The pivot element is shown at 52 and receives the eye 53 of theplunger 54. The block is shown at 55 and the yoke is shown at 56, theadjusting screws appearing at 57 and the jaws being shown at 58.

The extension 10 may be detached from the shank 5 and the hook 1e may beengaged with the edge of a tire on a wheel. Then when the handle portion11 of the extension is pressed down, the end of the lever 15 near thehook 14: will be pressed against the fiat countersunk head of a tirebolt and will hold ti]? same while the nut on the bolt is taken 0 Havingthus described the invention, what is claimed is 1. In a device of theclass described, a pair of pivotally connected levers; jaws pivoted tothe levers and provided with cutting means and with holding means; andmeans for pivotally connecting the jaws between the holding means andthe cutting means, whereby when the levers are pressed together at theirfree ends, the cutting means of the respective jaws will move towardeach other and the holding means of the respective jaws will move awayfrom each other; one lever including an offset, removable eX- tensionadapted for lateral reversal on that lever of which the extensionconstitutes a part, thereby to effect a crossing of the levers and tocause the holding means of the respective jaws to move toward each otherwhen the free ends of the levers are pressed together.

2. In a device of the class described, a pair of levers; a pivot elementconnecting the levers; jaws pivoted to the levers; a fulcrum member towhich the jaws are pivoted; and a plunger mounted on the pivot elementand adapted to reciprocate in the fulcrum member, the plunger beingresilient Note Fig. 11. In this figure, the

and being laterally flexible to relieve an undue strain upon the jaws.
